HttpWebRequest chunked/async POST

Question

Hi I want to upload some dynamic generated content to my web api. On the client I use the HttpWebRequest. The data should be uploaded sync and I want to write to the stream

Answer 1

You are using objects of an HttpWebRequest on multiple threads concurrently. response is a task that runs concurrently with your writes. That is clearly thread-unsafe.

Also, I don't see what you want to achieve. HTTP has a request-then-response model. The server can't (usually) send a single response byte before receiving the entire request. Theoretically, this is possible. But that is very unusual and likely not supported by the .NET BCL. This would only be supported by a (very unusual) custom HTTP server of yours.
